[0008] Embodiments of the disclosed subject matter generally relate to systems, devices, and methods for foaming dispensing liquids, e.g., liquid soap, liquid detergent, liquid cosmetic compositions, liquid hair compositions, or liquid skin care compositions, e.g., lotions, creams, or emulsions. Thus, embodiments may include foaming dispensers or foaming arrangements that incorporate foaming dispensers.

[0009] Embodiments of the disclosed product can produce a low-pressure, granular or highly viscous foam. The liquid component can contain one or more additives, including powders, particles, and / or abrasives, such as solid polymer particles, waxes, UV scattering agents, solid oil particles, silica, or organic substances. Optionally, the additive(s) can be added to the liquid component before it reaches a mixing chamber. The size of the powder, particles, and / or abrasives can range from 0.001 µm to 1000 µm, preferably from 0.1 µm to 700 µm, and more preferably from 0.5 µm to 500 µm. The size can refer to the particle diameter, which generally means the radius of a sphere. The powder or particle size can be obtained by measuring a distribution of the powder or particles using a laser diffraction scattering method, for example with a model LA-920 from Horiba, Ltd.Additionally or alternatively, the viscosity of the liquid contents at 25 °C can be, for example, 0.01 to 20 Pa s (10 centipoise to 20,000 centipoise), preferably 0.02 to 10 Pa s (20 centipoise to 10,000 centipoise), and more preferably 0.03 to 2 Pa s (30 centipoise to 2,000 centipoise) in embodiments of the disclosed article. Furthermore, embodiments of the disclosed article can reduce or prevent clumping of cleaning agents, for example, at least before they reach a mixing chamber. The viscosity (e.g., at 25 °C) can be measured by a type B viscometer with, for example, a rotational speed of 1 rpm. The type of rotor and the rotational speed can be selected based on a viscometer model and viscosity grade.

[0010] In general, embodiments of the disclosed object can provide several liquid flow channels and one or more separate air channel(s), so that the liquid contents and air can first meet or come into contact with each other in the mixing chamber to foam the liquid contents for dispensing. The air-liquid mixing ratio can be between 10 and 40 liters.

[0011] For example, embodiments of the disclosed object may generally include: a dispenser for foaming the dispensing of a liquid content by mixing an airflow from an air chamber with the liquid content flow from a liquid chamber. The foaming dispenser may have: a mixing chamber configured to mix air and liquid content; a porous section between an air channel from the air chamber and the mixing chamber; and a liquid channel from the liquid chamber to the mixing chamber. The liquid channel may have a first liquid channel and several second liquid channels. The liquid channel may be configured such that liquid content flows from the first liquid channel to the second liquid channels and into the mixing chamber.The secondary liquid channels can be configured to allow or provide for the flow of the contents liquid to the mixing chamber in at least two directions. Optionally, the secondary liquid channels can enter the mixing chamber relatively close to an outlet side of the porous section, which may form the outlet from the air channel. Optionally, the liquid channel can have one or more intermediate liquid channels between the primary liquid channel and the secondary liquid channels.

[0012] In one or more embodiments, a dispenser may have a mounting element (e.g., a bracket) configured to secure or hold the porous part. The mounting element may be located on a downstream side of the porous part. The mounting element may be attached to or held in place on the porous part, for example, by atmospheric pressure. The mounting element may prevent or reduce downstream movement of the porous part due to atmospheric pressure. Furthermore, the secondary fluid channels may be located below and / or within the mounting element. That is, the mounting element may form some or all of the secondary fluid channels. Preferably, the mounting element may have concave sections and may form the secondary flow channels between the concave sections and the porous part.The fastening part can be fitted into a hollow body of the foam dispenser, which forms at least one section of the mixing chamber.

[0013] Embodiments of the disclosed object may include pump foamers and press foamers. Generally, a pump foamer may have an air chamber and a separate liquid chamber and may operate by dispensing foamy liquid via the actuation of a mechanical pump. Generally, a press foamer may have a common air and liquid chamber and may operate by dispensing foamy liquid into the common air and liquid chamber via a press action.

[0014] With reference to the drawings, we now show Fig. 1A and Fig. 1B each a sectional view of a section of a pump foamer arrangement 100 according to one or more embodiments of the disclosed object.

[0015] The pump-type foamer assembly 100 can be a pump-type foamer assembly and can comprise: a cap dispensing head 102, a cap neck 104, an air chamber 106, an air cylinder 108, an air piston 110, an air valve 112, a shaft 114 to a liquid chamber of a liquid container (both not shown separately), a liquid cylinder 116, and a liquid piston 118. The pump-type foamer assembly 100 can further comprise a foaming dispenser according to embodiments of the disclosed object, which is located in Fig. 1A and Fig. 1B is not specifically shown, but may be provided in the foaming area 130. Furthermore, the pump foamer arrangement 100 may have the liquid container to hold the contents liquid, e.g. liquid soap, and the liquid container may be removably coupled to the cap neck 104 via a container neck 144.

[0016] How Fig. 1A and Fig. To illustrate in general terms, the pump foamer arrangement 100 can realize the air chamber 106, the air cylinder 108, the air piston 110 and the air valve 112 in such a way that they operate as a mechanical pump which reacts to downward and upward movement of the cap dispensing head 102 in order to cause air 105 in the air chamber 106 to be transported to the foaming area 130 via an air flow path 113 and dispensed via the cap dispensing head 102. Similarly, the pump-foamer arrangement 100 can configure the shaft 114, the liquid cylinder 116, and the liquid piston 118 to function as a mechanical pump that responds to downward and upward movement of the cap dispensing head 102, causing the contents liquid 119 in the liquid container to move through the shaft 114 and be transported to the foaming area 130 via a liquid flow path 120. As shown in Fig. As can be seen from Figure 1A, the airflow path 130 and the liquid flow path only meet when they reach the foaming area 130, in particular a mixing chamber, which will be discussed in more detail later.

[0017] In this context, the cap dispensing head 102 can be referred to as a pressure element. Generally, when the cap dispensing head 102 is pressed down, for example by a user's hand, a quantity of foamy liquid can be dispensed from the cap dispensing head 102. As the cap dispensing head 102 rises, air 105 can be supplied to the air chamber 106, and liquid 119 can be supplied to the liquid cylinder 116. Based on the configuration of the cap dispensing head 102, the flow of foamy liquid 101 from the mixing chamber to a dispensing opening of the cap dispensing head 102 can be vertical and then horizontal to reach the dispensing opening.

[0018] Fig. Figure 2A is a schematic representation of a foaming dispenser 200 according to one or more embodiments of the disclosed object, and Fig. 2B is an enlarged section of the 200 foam dispenser. Fig. 2A.

[0019] The foam dispenser 200 can have a mixing chamber 210, a porous part 220, and a liquid channel 230. The mixing chamber 210 can be formed by at least a mixing chamber body 212 and a surface of the porous part 220 at an outlet 222 of the porous part 220.

[0020] In general, the foam dispenser 200 can be described as an air-passage foam dispenser, meaning that air 240 is directed to an inlet 221 of the porous part 220, through the porous part 220, and discharged from the outlet 222 of the porous part 220 to enter the mixing chamber 210. Furthermore, the foam dispenser 200 can foam the contents liquid by mixing air 240 with the contents liquid 231 to produce a foamy contents liquid 201. Optionally, according to the schematic diagram in Fig. 2B the foamy liquid contents 201 contain or be equipped with cleaning agents 202, e.g., powders, particles and / or abrasives. The air 240 can be supplied from an air chamber (not shown separately), and the liquid contents 231 can be supplied from a liquid chamber (not shown separately).

[0021] The fluid channel 230 can have a first fluid channel 232 and one or more second fluid channels 234. In this respect, they show Fig. 2A and Fig. 2B only one second liquid channel 234; however, embodiments of the disclosed object are not limited to a single second liquid channel 234 and may preferably have several second liquid channels 234, and even more preferably have four second liquid channels 234. In the case of several second liquid channels 234, the second liquid channels 234 may be configured to allow or provide for the flow of the contents liquid 231 in at least two directions. Each second liquid channel 234 may lead to the mixing chamber 210 via an opening 235, which may be formed in the mixing chamber body 212. The openings 235 may be provided at the outlet 222 of the porous part 220, for example, adjacent to the outlet 222 of the porous part 220.

[0022] Optionally, in one or more embodiments, the second liquid channels 234 can have at least one pair of second liquid channels 234 that discharge the contents liquid 231 in opposite directions, and preferably two pairs of second liquid channels 234 that discharge the contents liquid 231 in respective opposite directions.

[0023] The first liquid channel 232 can intersect the second liquid channels 234. For example, an end section of the first liquid channel 232 can be adjacent to a first end section of each second liquid channel 234, and a second end section of the second liquid channels 234, opposite to the first end section, can be in direct fluid communication with the mixing chamber 210. Thus, a first direction in which air is guided from the porous part 220 to the mixing chamber 210 can intersect a second direction in which the liquid content 231 is discharged from each of the second liquid channels 234 to the mixing chamber 210.

[0024] The porous part 220 can be configured to allow air to pass through while preventing the liquid 231 from passing through (from the outlet 222 of the porous part 220, since the liquid 231 does not contact the inlet 221 of the porous part 220). This allows the porous part 220 to take in air 240 at its inlet 221, allow the air to pass through, and discharge the air from its outlet 222 to the mixing chamber 210. Optionally, the porous part 220 can have a mean pore size of 20 µm to 100 µm. The porous part 220 can be made of a porous material, including mesh, gauze, foam, sponge, or a combination of two or more materials.Furthermore, the porous part 220 can be arranged above the first liquid channel and below the mixing chamber 210, and the porous part 220 can, for example, have the form of a flat plate, a flat ring, or a flat disc. Optionally, the porous part 220 can be attached to the mixing chamber or be designed to be removable relative to it.

[0025] Air can be released from outlet 222 of the porous part 220 to cross the liquid 231, which is discharged from the second liquid channels 234 to the mixing chamber 210. This crossing can produce the foamy liquid 201. As mentioned previously, the liquid 231 and the air 240 can also enter or be supplied to the mixing chamber 210 simultaneously for the first time. In other words, the air 240 and the liquid 231 can come into contact with each other for the first time in the mixing chamber 210. Furthermore, the liquid 231 can bypass the inlet 221 of the porous part 220, or in other words, reach the mixing chamber 210 without passing through the porous part 220.

[0026] Fig. Figure 3 is a sectional view of a foaming dispenser 300 according to an embodiment of the disclosed object.

[0027] The foam dispenser 300 can have a mixing chamber 310, a porous part 320, and a liquid channel 330. The mixing chamber 310 can be formed by at least a mixing chamber body 312 and a surface of the porous part 320 at an outlet 322 of the porous part 320. In general, the foam dispenser 300 can be described as an air-passing foam dispenser, meaning that air 340 is directed to an inlet 321 of the porous part 320, passes through the porous part 320, and is discharged from the outlet 322 of the porous part 320 to enter the mixing chamber 310. The air 340 can also be directed through an air interface 314 via one or more openings. Furthermore, the foaming dispenser 300 can foam the liquid content 331 by mixing air emitted from the porous part 320 with the liquid content 331 to produce a foamy liquid content 301. Although Fig. Figure 3 shows a sectional view, it should be noted that the air 340 and the liquid contents 331 only mix when they each reach the mixing chamber 310.

[0028] The fluid channel 330 can have a first fluid channel 332 and several second fluid channels 334. In particular, it shows Fig. 3 two second fluid channels 234, but there Fig. As shown in Figure 3, which depicts a sectional view, the foam dispenser 300 can, for example, have four secondary liquid channels 334, each with a corresponding opening 335 leading into the mixing chamber 310. Thus, the secondary liquid channels 334 can provide or enable the flow of the contents liquid 331 into the mixing chamber 310 in at least two directions, for example, four flow directions. Optionally, opposing pairs of secondary liquid channels 334 can dispense contents liquid 331 in opposite directions, in this example inwards, for example, radially inwards. Furthermore, each of the openings 335 can be provided at the outlet 322 of the porous part 320, for example, adjacent to the outlet 322 of the porous part 320. Optionally, the air 340 of the mixing chamber 310 can be supplied inwards from the respective openings 335 of the secondary liquid channels 334 at the outlet 322 of the porous part 320.In one or more embodiments, each of the second fluid channels 334 may optionally have a section (or sections) formed at a right angle to the first fluid channel 332.

[0029] Optionally, a cross-sectional area perpendicular to each of the second liquid channels 334 can be smaller than a cross-sectional area perpendicular to the first liquid channel 332. For example, sections of the second liquid channels 334 can have a thickness T1, which can be, for example, 0.9 mm, where the thickness T1 can also correspond to a thickness of the openings 335, and the first liquid channel 332 can have a maximum cross-sectional dimension MD (e.g., diameter) of, for example, 2 mm. Alternatively, a total cross-sectional area of ​​all second liquid channels 334 can be smaller than a total cross-sectional area perpendicular to the first liquid channel 332. Furthermore, optionally, a total surface area of ​​the porous part 320 at the outlet 322 of the porous part 320 can be larger than a total cross-sectional area of ​​the respective openings 335 to the mixing chamber 310 of the second liquid channels 334.

[0030] Fig. Figure 4 is a sectional view of a foaming dispenser 400 according to an embodiment of the disclosed object.

[0031] The foam dispenser 400 can have a mixing chamber 410, a porous part 420, and a liquid channel 430. The mixing chamber 410 can be formed by at least a mixing chamber body 412 and a surface of the porous part 420 at an outlet 422 of the porous part 420. In general, the foam dispenser 400 can be described as an air-passing foam dispenser, meaning that air 440 is directed to an inlet 421 of the porous part 420, passes through the porous part 420, and is discharged from the outlet 422 of the porous part 420 to enter the mixing chamber 410. Furthermore, the foaming dispenser 400 can foam a liquid content 431 by mixing air emitted from the porous part 420 with the liquid content 431 to produce a foamy liquid content 401. Although Fig. Figure 4 shows a sectional view, it should be noted that the air 440 and the liquid contents 431 only mix when they each reach the mixing chamber 410.

[0032] The liquid channel 430 can have a first liquid channel 432 and a second liquid channel 434. In particular, it shows Fig. 4 a central projection 414 that extends through an opening in the porous part 420 and into the mixing chamber 410. This allows a section of the central projection 414 extending from the porous part 420 to form part of the mixing chamber 410. Furthermore, the central projection 414 can be hollow and form the first liquid channel 432 and the second liquid channels 434. Additionally, the porous part 420 can be arranged radially outward from a section of the first liquid channel 432, which is formed, for example, by the central projection 414.

[0033] Fig. Figure 4 shows two second liquid channels 434, but there Fig. As shown in Figure 4, which depicts a sectional view, the foam dispenser 400 can, for example, have four secondary liquid channels 434, each with a corresponding opening 435 leading into the mixing chamber 410. Thus, the secondary liquid channels 434 can provide or enable the flow of the liquid 431 into the mixing chamber 410 in at least two directions, for example, four flow directions. Optionally, opposing pairs of secondary liquid channels 434 can dispense the liquid 431 in opposite directions, in this example outwards, for example, radially outwards. Furthermore, air 440 can be supplied to the mixing chamber 410 at the outlet 422 of the porous part 420, radially outwards from the openings 435 of the secondary liquid channels 434.

[0034] Furthermore, each of the openings 435 can be provided at the outlet 422 of the porous part 420, for example, adjacent to the outlet 422 of the porous part 420. Alternatively, each of the openings 435 can be offset from the outlet 422 of the porous part 420 by an offset height H2. In one or more embodiments, each of the second fluid channels 434 can optionally have a section (or sections) formed at a right angle to the first fluid channel 432.

[0035] Optionally, a cross-sectional area perpendicular to each of the second liquid channels 434 can be smaller than a cross-sectional area perpendicular to the first liquid channel 432. For example, sections of the second liquid channels 434, e.g., openings 435, can have a thickness T2, which can be, for example, 1 mm, and the first liquid channel 432 can have a maximum cross-sectional dimension MD (e.g., diameter) of, for example, 2 mm. Alternatively, a total cross-sectional area of ​​all second liquid channels 434 can be smaller than a total cross-sectional area perpendicular to the first liquid channel 432. Furthermore, optionally, a total surface area of ​​the porous part 420 at the outlet 422 of the porous part 420 can be larger than a total cross-sectional area of ​​the respective openings 435 to the mixing chamber 410 of the second liquid channels 434.

[0036] Fig. Figure 5 is a sectional view of yet another foam dispenser 500 according to one or more embodiments of the disclosed object. The foam dispenser 500 is similar to the foam dispenser 400 in Fig. 4 with the exception of the configuration of the central projection 514 and a support 515. Thus, the foam dispenser 500 can have a mixing chamber 510, a porous part 520, and a liquid channel 530. The mixing chamber 510 can be formed by at least a mixing chamber body 512 and a surface of the porous part 520 at an outlet 522 of the porous part 520. In general, the foam dispenser 500 can be described as an air-passing foam dispenser, meaning that air 540 is drawn to an inlet 521 of the porous part 520, passes through the porous part 520, and is discharged from the outlet 522 of the porous part 520 to enter the mixing chamber 510. Furthermore, the foaming dispenser 500 can foam the liquid content 531 by mixing air emitted from the porous part 520 with the liquid content 531 to produce foamy liquid content 501. Although Fig. As shown in Figure 5, a sectional view, it should be noted that the air 540 and the liquid 531 only mix when they each reach the mixing chamber 510. Thus, air 540 can be guided to an inlet 521 of the porous part 520, through the porous part 520, and discharged from the outlet 522 of the porous part 520 to enter the mixing chamber 510. Furthermore, the foaming dispenser 500 can foam the liquid 531 by mixing air discharged from the porous part 520 with the liquid 531 to produce foamy liquid 501. Fig. Figure 5 shows a sectional view, it should be noted that the air 540 and the liquid contents 531 only mix when they each reach the mixing chamber 510.

[0037] The liquid channel 530 can have a first liquid channel 532 and several second liquid channels 534. In particular, it shows Fig. 5 a central projection 514 which projects through an opening in the porous part 520, but not necessarily into the mixing chamber 510. Of course, a top section of the central projection 514 can be interpreted as forming part of the mixing chamber 510. Furthermore, the central projection 514 can be hollow and form the first liquid channel 532. The support 515 can have feet 516, for example four or six, which form the second liquid channels 534. In one or more embodiments, the number of second liquid channels 534 formed by the support 515 can be two to ten, preferably four to eight. The porous part 520 can be arranged radially outward from a section of the first liquid channel 532, which is formed, for example, by the central projection 514. The holder 515 can also be configured to hold the porous part 520 in the mixing chamber 510.For example, the support 515 can prevent the porous part 520 from moving upwards (i.e. downstream) in the mixing chamber 510.

[0038] Fig. Figure 5 shows two second fluid channels 534 formed between the feet 516 of the bracket 515. Since Fig. As shown in Figure 5, which depicts a sectional view, the foam dispenser 500 can, for example, have four secondary liquid channels 534, each formed between adjacent feet 516 of the support 515. The secondary liquid channels 534 formed between adjacent feet 516 can provide for the flow of the liquid 531 into the mixing chamber 510 in at least two directions, for example, four or more flow directions. Optionally, opposing pairs of secondary liquid channels 534 can dispense liquid 531 in opposite directions, in this example outwards, for example, radially outwards. Furthermore, air 540 can be supplied to the mixing chamber 510 at the outlet 522 of the porous part 520 through the openings 535 of the secondary liquid channels 534. Furthermore, each of the openings 535 can be provided at the outlet 522 of the porous part 520, for example adjacent to the outlet 522 of the porous part 520.In one or more embodiments, each of the second liquid channels 534 can optionally have a section (or sections) formed at a right angle to the first liquid channel 532. For example, the height H can be 0.3 to 3 mm, preferably 0.3 to 2.5 mm. Thus, the height of the openings 535 can be 0.3 to 3 mm, preferably 0.3 to 2 mm.
